To ctZZ whom t uta/y concern:

Be it known that I, GEORGE H. HLETT, a resident cf Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Oar-Dumping Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains 1o to make and use the same.

My invention relates to an improvement in car-dumping machines.

In pending application, Serial No. 614,232, filed December 2,1876, by John McMyler and myself, We show and describe a car-platform adapted to be tilted to discharge the contents of the car over the side of the car, combined with clamps for clamping one side of the car to the platform and with counterwe'ghtedl zo chains adapted to engage the other or ed side of the car Vand hold the car solidly on the platform. We also described and claimed a laterally-movable platform mounted on the tilting platform and connected with counter- `5 Weighted chains, the parts being so constructed and arranged to force the car-platform laterally, so as to bring the car under the clamps as the tilting platform begins its upward movement. In the device above referred to the counterweighted chains coming in direct contact with the outer side of the car or against the side opposite the side over which the coal is discharged and closely embracing said side tends to crush and bend the side, and particularly so if the body is constructed of sheet metal and light angle-irons now largely used in car construction.

One object, therefore, of the present invention is to provide means for preventing in- 4o jurious crushing strain of the chains against the car-body.

A further object is to provide improved means for yicldingly forcing the laterallymovable car-platform in a position to bring the side of the car over which the material is discharged under the clamps.

With these ends in View my invention consists in the parts and combinations of parts, as will be more fully explained, and pointed 5o out in the claims.

In the accompanyn g drawings, Figure l is a View in end elevationof my improved apparatus, showing in solid lines the normal position of the parts and in dotted lines the positions of the parts during the operation of dumping. Fig. 2 is a detached view of the clamp; and Fig. 3 is a detached vieri showing the mechanism for forcing the car-platform laterally, so as to carry the car overl against the side clamps. Fig. 4t is an elevation of the cradle and platform, the latter being partly in section and showing the devices for moving the platform laterally towardthe upright portion of the cradle.

l represents a frame or tower, and 2 a tilting platform L-shaped in end View and pivoted at 3 to the stationary posts or supports 7. The horizontal member of the tilting platform r2 rests solidly on a suitable foundation, girdersyorother supports when in the posi` tion shown in solid lines in Fig. l, and carries on its upper surface the laterally-movable car-platform 4. The car platform is mounted on rollers, as disclosed in the application above referred to, so as to permit it to move laterally or transversely, and. is provided With the depending extensions or proj ections 6, adapted to engage fixed abutm ents 8 and limit the inward movement of the carplatform. The details of the spring meehanism for forcing the car-platform laterally are shown in Figs. 3 and 4. A bar 6 is secured at one end to the platform 4t and projects loosely into a sleeve b, mounted in the end b of said platform, said sleeve being adapted to bear against the girder c, which constitutes a fixed part of the tilting platform or cradle 2. A spring 5 is disposed on the bar 6 and bears at one end against a head e at one end of said bar. The other end of the spring bears against a collar 5, disposed loosely on the bar 6, and said collar bears against one end of the sleeve Z9, the latter being strengthened and its end broadened or thickened by means of a collar f' secured thereto. i

From the construction it will be seen that as the pivoted platform 2 is turned on its pivot or pivots 3 thesprings 5, bearing against the shoulder or head e, secured to` the carn platform e, forces said platform 4. laterally ico until the car comes in contact with the verf- Y tical side member of the pivoted platform 2 or with the vertical members of the clamps and holds the car-body thereagainst until the platform descends. As the platform descends and as it nears its normal position the projections 6 of the car-platform strike the abutments 8 and move the car-platform laterally outward, thus compressing the springs and moving the car-body away from the vertical member of the pivoted platform. The pivoted platform is tilted or tipped by the 'cables or chains 26, each secured at one end to the brackets 27, fixed to the pivoted platform, preferably at the lower edge of the vertical member thereof. These chains or cables pass under sheaves 2S at the outer ends of the pivoted platform, up over sheaves 25 on the upper part of the frame l, and down to the hoisting-drum 24.

The clamp for clamping the car to the platform during the operation of tilting the car to discharge its load is shown detached in Fig. 2. These clamps, preferably four, are arranged at intervals throughout the length of the tilting platform, and each is composed of two main partsl A and B, the former of which is adapted to engage the top edge of the car-body, over which the material is discharged, while the latter engages the opposite top edge and operates to hold the flexible chain out of immediate contact with the carbody. The sections A of each clamp is mounted in a guide C, carried by the tilting platform, and each clamp is provided at its upper end with a clamping-j aw fand at its lower end with, preferably, a roller 22. The rollers normally rest on the roller-path 23, formed in or on the base of the apparatus, and when the tilting platform is in its normal position (shown in Fig. l) the rollers, by reason of their engagement with the roller-paths, hold the clamping-jaws f elevated, so as to receive thereunder the maximum size car-body. As the platform begins to turn the clamps descend by reason of gravity until the jaws f thereof rest on the top edge of the car-body.

Pivoted at 16 to the upper ends of the clamps B are the clamps A. These clamps B are provided at their free ends with the bearings D, which latter are elongated, so as to compensate for or take in the various widths of carbodies now in general use.

Secured to brackets g on the vertical members of the pivoted platform are the counterweighted chains 14, each of which passes upwardly in a groove in the rear of its clamp A, passes over a sheave at the juncture of the clamps B and A, between sheaves 17 and 18, carried in the outer end of the clamp B, over sheave 19 in the frame or tower l to its counterweight 11. From this it will be seen that the chains cross over the car, and the countei-weights hold the several clamps elevated, so as to-permit a car to pass freely thereunder. When, however, the platform is tilted, it will be seen that the chains crossing over and bearing against the tops of clamps A force the jaws f down onto the edge of the car-body and hold that side of the car solidly in place, and as the tilting movement is continued the outer edge of the car-body contacts with the seats D of the clamps B, and as the chains 14 are by this time exerting a downward pull on the sheaves 17 it will be seen that the clamp B is held solidly on the top of the car, and particularly the outer side edge thereof, thus forming a rigid cradle in which the car rests when it is in its dumping position, as shown by dotted lines in Fig. 1. Vith this construction the` flexible chain is held out of coutact with the car-body, and the collapsing strains to which the car-body is subjected when supported in iiexible chains is avoided.

It is evident that numerous slight changes might be made in the general form and arrangement of the several parts herein shown and described without departing from the spirit and scope of my invention, and hence l would have it understood that I do not limit myself to the precise details herein set forth,

but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a fixed frame, a tilting platform and means for tilting the platform of a laterally-movable car-platform having projections adapted to engage the fixed frame for holding the car-platform against movement in one direction and a spring for moving said car-platform in the one direction.

2. The combination with a fixed frame, a tilting platform, of a laterally-movable carplatform having projections adapted to engage the fixed frame for holding the platform against movement in one direction, springs for forcing said car-platform laterally in one direction and counterweighted chains for supporting the car-body against the platform when the latter is tilted.

3. The combin ation with a tilting platform, of means for tilting the platform, counterweighted chains constructed and adapted to embrace a car on the platform when the latter is tilted, and a rigid top clamp carried by the chains and adapted to engage the outer side edge of the top of the car.

4. The combination with a tilting platform, of means for tilting the platform, side clamps, counter-weighted chains automatically operating said clamps for engaging the inner side of the car and top clamps carried by said side clamps and by the counterweighted chains.

5. The combination with a tilting platform and means for tilting same, of gravity-clamps for engaging one side of the top of the carbody, top clamps carried at one end by the upper ends of the gravity-clamps, and counterweighted chains supporting the outer ends of said top clamps.

6. The combination with a tilting platform and means for tilting same, of a series of side IIO n www oar-bodywhen the latter is tilted.

8. The combination with a tilting platform and means for tilting same, of a series of vertical clamps adapted to rest normally on stationary seats, rollers on the lower ends of said clamps, top clamps pivoted to the upper ends of the Vertical clamps, and eounterweiglnted chains connected to said Clamps, substantially as set forth. i

In testimony whereof I have signed this specification in the presence of two subscribing Witnesses.
